Loading variables issue

easy and simple code. it’s not suposed to give so much problems, look:

—textos.txt [coded in unicode]—
introtxt=text one, all right
&expl=text two, all right, right?

—actionscript [2.0] inside the first and only frame of a m.c. called ‘txt’—
loadVariables(“textos.txt”, this);
exptxt = expl;

there’s a dynamic text box with the variable exptxt, and still when i test it, i see ‘undefined’ - but if i put expl as variable of the text, it loads it perfectly. then it loads the vars for the screen and not the action script? or what? how do i solve this?
